A Riddle Wrapped in an Enigma
In August 2015 the U.S. National Security Agency (NSA)
released a major policy statement on the need for post-quantum cryptography (PQC). This announcement will be a great stimulus to the
development, standardization, and commercialization of new quantumsafe
algorithms. However, certain peculiarities in the wording and timing
of the statement have puzzled many people and given rise to much
speculation concerning the NSA, elliptic curve cryptography (ECC), and
quantum-safe cryptography. Our purpose is to attempt to evaluate some
of the theories that have been proposed
Ruprecht 106: A riddle, wrapped in a mystery, inside an enigma
Galactic globular clusters (GCs) show overwhelming photometric and
spectroscopic evidence for the existence of multiple stellar populations. The
question of whether or not there exists a GC that represents a true 'simple
stellar population' remains open. Here we focus on Ruprecht 106 (R106), a halo
GC with [Fe/H]=-1.5 and [alpha/Fe]~0. A previous spectroscopic study found no
sign of the Na-O anticorrelation among 9 of its brightest red giants, which led
to the conclusion that R106 is a true simple stellar population GC. Here we
present new Hubble Space Telescope (HST) Wide Field Camera 3 photometry of R106
that, when combined with archival HST images spanning a 6-year baseline, allows
us to create proper motion cleaned color-magnitude diagrams spanning the
ultraviolet (F336W) to the near-infrared (F814W). These data allow us to
construct the pseudo-color C_{U,B,I} that is sensitive to the presence of
light-element abundance spreads. We find no evidence of a split along the red
giant branch (RGB) in the C_{U,B,I} diagram but the width of the RGB
(sigma_CUBI = 0.015) is marginally broader than expected from artificial star
tests (sigma_CUBI = 0.009). The observed spread in C_{U,B,I} is smaller than
any other Galactic GC studied to date. Our results raise important questions
about the role of formation environment and primordial chemical composition in
the formation of multiple stellar populations in GCs.Comment: 11 pages, 5 figures, accepted versio
Somatization: A Riddle Wrapped Up in an Enigma
A propensity to experience psychological distress and their expression in the form of somatic symptoms and to seek medical help for them is called Somatization. It is basically an inception of some psychiatric conditions like Affective Disorders (anxiety and depression) and Somatoform Disorders. A Somatoform Disorder is a category of mental disorder in which physical symptoms that suggest physical condition or injury cannot be explained fully by a general medical condition. This possibility must always be considered when patient has recurring somatic complaints for at least six months. Depression and Somatic Symptoms Disorder can easily be recognized when they present separately or in association with each other. But the main hurdle is to develop a holistic approach and strategy to not be misguided by the intimidating nature of presenting physical symptoms. For that detailed evaluation should be carried out and every single possibility along with somatization should be kept under consideration, which would enable to recognize and treat the illness earlier and save considerable amount of time and resources as well
The SS-20: A Range of Choices
Winston Churchill\u27s often quoted observation that the Soviet Union is a riddle wrapped in a mystery inside an enigma would appear to have some validity even today. In any case the confrontational nature of relations between the United States and the Soviet Union make it prudent to follow the good advice of an even older strategist, Sun Tzu, that it is necessary to ...know one\u27s enemy if success is to be assured
Driving Force of the Ukraine Crisis
For many people in North America, trying to understand what is taking place in Eastern Europe between Russia and Ukraine can be a bit confusing. Even Winston Churchill once described this part of Europe as a riddle wrapped in a mystery inside an enigma.

Why can't China clean up its act?
Winston Churchill once described the Soviet Union as 'a riddle
wrapped in a mystery inside an enigma.’ Modern China is a very
different story. By definition, the workings of the world’s largest
economy (by purchasing power parity) can’t really be hidden from
view nearly as easily. However, the sheer scale means that certain
aspects of that vast market’s workings are still not all that easy
to understand
Twenty years of KSHV
Twenty years ago, Kaposi’s sarcoma (KS) was the oncologic counterpart to Winston Churchill’s Russia: a riddle, wrapped in a mystery, inside an enigma. First described by Moritz Kaposi in 1872, who reported it to be an aggressive skin tumor, KS became known over the next century as a slow-growing tumor of elderly men—in fact, most KS patients were expected to die with the tumor rather than from it. Nevertheless, the course and manifestations of the disease varied widely in different clinical contexts. The puzzle of KS came to the forefront as a harbinger of the AIDS epidemic. The articles in this issue of Viruses recount progress made in understanding Kaposi’s sarcoma herpesvirus (KSHV) since its initial description in 1994
Legal Reform and the Chongquing Effect: Two Steps Forward One Step Back?
For those steeped in the Western legal tradition, the Chinese political and legal system is, in the famous words of Winston Churchill, a riddle wrapped in a mystery inside an enigma.1 Of course, Churchill was describing the potential actions of Russia, not China.2 But, to continue borrowing from Churchill, perhaps there is a key – Chinese national interest and the interest of the Chinese Communist Party.3 This research explores the interaction between political, economic, and legal reform, and posits that the Chongqing incident4 was ultimately a positive turning point in the country’s institutional development. The theory presented herein is that although some argue the manner in which the Bo Xilai trial5 was conducted, and its aftermath, represents a step back in political aperture, it is actually an example of the “two steps forward, one step back”6 so closely associated with Communist political regimes in transition, and holds promise for consolidation of institutional reform in China. In exploring the riddle, this article attempts to place the Chinese legal system in its historic context before moving to the inextricable relationship between law and politics in China. Finally, it is argued that the Bo Xilai prosecution, while undeniably politically motivated and rife with retrograde elements, was also a cautious but definitive move towards the triumph of a new model of consolidated institutionalization
